Double

class Double : Number, Comparable<Double> (source)

An IEEE 754 binary64 floating-point value.

Supports finite values, signed zeros, infinities and NaN. Mixed arithmetic promotes numeric operands to Double and may round large integers. MIN_VALUE is the smallest positive subnormal value, not the most negative value. compareTo orders NaN above numbers and negative zero below positive zero; primitive equality treats NaN as unequal and both zeros as equal.
